Most of the old Ford stores have either bushing kits or king pin kits. Try Macs. or www.Speedwaymotors.com. Also has kits.

Thank you exactly what I needed to know.

These are floating bushings. Their split and easily push in with only hand pressure. I pressed them out with a socket's and a vise. They came out with very little pressure. They have a steel backing with bronze sleeve. I don't think this type requires reaming.

Thank you.

King Pin Questions

Previously I had posted in my journal that my king pins and spindles came apart with ease. Today I broke them down further removing the bushing inserts and measured everything up. The king pins themselves measure .811”.

What is the free play tolerance suppose to be between the king pin and the bronze bushings? Also is there a site where I can by the new bushings, or should I just head down to the local bearing shop to buy the bushings.
